We thought they couldn’t top the original, but this is the funniest thing we’ve ever seen!

Justin Timberlake joined Jimmy Fallon on the set of his talk show July 19, and they surprised the audience with an amazing mash-up of their fave rap songs — starting with the 80’s!

The duo’s first ‘history of rap’ medley aired back in September of 2010, so it’s about time they revamped their routine. They obviously have great chemistry performing together, but then again, any performance looks great with Justin Timberlake‘s swag in it!
